Abstract
In article the cathodic cleaning processes of aluminum alloyAW 5754 and cleaned substrate surface coating by plasmawith Ni-Cr-Fe-Si powder were researched. Aluminium substrateroughness after cathodic treatment at different cathodic treatmentparameters was established during the experiments. During theinvestigation a comparison of the calculated medium power1.6 to 9 kW plasma torch voltage-current characteristics withthe experimental results was made. The optimized parametersof aluminium cathode substrate cleaning process were selected;porosity and morphology of plasma sprayed nickel-based coatingwere determined.

Straipsnyje nagrinėjami aliuminio lydinio AW 5754 katodinio valymo procesai ir nuvalyto substrato paviršiaus dengimas plazminiu būdu Ni-Cr-Si-Fe danga. Eksperimentinių bandymų metu nustatytas aliuminio substrato šiurkštumas po katodinio valymo, esant skirtingiems katodinio valymo parametrams. Tyrimo metu buvo palygintos apskaičiuotos vidutinės galios 1,6–9 kW plazmotrono voltamperinės charakteristikos su eksperimentiniais rezultatais. Parinkti aliuminio substrato optimalūs katodinio valymo proceso parametrai ir nustatytas plazminiu būdu užpurkštos nikelio pagrindo dangos porėtumas ir morfologija.
